Summary
In Dzulkarnain bin Khamis v Public Prosecutor ([2023] SGCA 14), the Court of Appeal dismissed two criminal appeals arising from the appellants’ joint trial for cannabis-related offences under the Misuse of Drugs Act (MDA). Both appellants were convicted in relation to possession of not less than 2375.1g of cannabis, with the case turning on whether the Prosecution proved the identity of the drug exhibits and the appellants’ knowledge of the nature of the drugs, as well as whether procedural and evidential objections undermined the trial judge’s findings.
The Court of Appeal upheld the High Court’s convictions and sentences. It affirmed that the trial judge properly rejected the defences and accepted the Prosecution’s evidence on the chain of custody and the relevant statutory presumptions. It also rejected Sanjay’s application to adduce fresh evidence on remittal, holding that the proposed evidence did not warrant reopening the case.
What Were the Facts of This Case?
The prosecution case concerned a sequence of events on 23 February 2015 involving two men, Dzulkarnain and Sanjay, and a brown box containing cannabis. Dzulkarnain drove a van to a bus stop near Tuas Checkpoint, where he collected a brown box (the “Brown Box”). Later that day, he drove to Lorong 21 Geylang and then to Lorong 37 Geylang. During the surveillance, one CNB team lost sight of the van temporarily, but another team continued to tail Dzulkarnain as he proceeded to Lorong 37.
At Lorong 37, CNB officers observed Dzulkarnain place the Brown Box behind a green dustbin marked with the number “14” (the “Green Bin”). This location was treated as the “drop-off point”. After Dzulkarnain left, Sanjay arrived at Lorong 37 within about five minutes. He stopped beside the Green Bin, retrieved a brown box from behind it (the “SKP Box”), returned to his car, and drove away. Sanjay was apprehended around 4.35pm near Lorong 36 Geylang, while Dzulkarnain was arrested shortly thereafter around 4.40pm at an Esso petrol kiosk.
After Sanjay’s arrest, officers conducted searches and recovered multiple exhibits from his person and vehicle, including the SKP Box containing five bundles of vegetable matter later analysed by the Health Sciences Authority to contain not less than 2375.1g of cannabis and 2329.1g of cannabinol and tetrahydrocannabinol. Officers also recovered handphones (marked SK-HP2 to SK-HP5), notebooks containing handwritten entries relating to drug transactions and prices, and weapons (two samurai swords and a knife). Before the SKP Box was opened, Sanjay was asked about its contents; he purportedly shrugged without verbalising an answer, which was recorded in a CNB field book as an “oral statement”.
As part of the seizure process, the SKP Box was opened and the bundles were removed and repacked into separate polymer bags, which were then placed into a green duffel bag (the “drug exhibits” and the “duffel bag”). Sanjay’s contemporaneous statement under s 22 of the Criminal Procedure Code was recorded from about 7.45pm to 8.30pm, in which he said he did not know what the SKP Box contained. Over the course of investigations, multiple other statements were recorded from Sanjay, and the defence later sought to exploit inconsistencies in his accounts. Notably, in a later long statement recorded on 8 March 2015, Sanjay departed from earlier explanations and claimed he had been told to take delivery of collectors’ hunting knives and that there “may also be contraband … cigarettes”.
What Were the Key Legal Issues?
The appeals raised several legal issues. First, Dzulkarnain challenged the trial judge’s finding that the box containing the drugs that Sanjay collected was the same box that Dzulkarnain had left at the drop-off point. This issue effectively concerned identity and the sufficiency of proof linking the observed Brown Box to the SKP Box seized from Sanjay.
Second, Sanjay advanced procedural and evidential complaints. He argued that the trial judge relied on statements that were not admissible when making findings. He also contended that the Prosecution’s case theory was not unified and was instead inconsistent and incompatible, thereby prejudicing his defence. These arguments required the Court of Appeal to consider how trial courts should evaluate evidence and whether any alleged procedural defects could undermine the convictions.
Third, Sanjay challenged the trial judge’s treatment of the statutory presumption under s 18(2) of the MDA. The presumption relates to knowledge of the nature of the drugs where a person is found in possession of controlled drugs. Sanjay argued that he had rebutted the presumption, and the Court of Appeal had to assess whether the evidence supported rebuttal on the balance of probabilities.
Finally, Sanjay filed Criminal Motion No 23 of 2022 seeking leave to adduce fresh evidence. The proposed evidence was his own account of the location of a duffel bag containing the drug exhibits seized from him, which he said would contradict a CNB officer’s testimony about custody. He sought remittal to the trial judge to take further evidence and provide findings on the chain of custody.
How Did the Court Analyse the Issues?
The Court of Appeal began by situating the appeals within the statutory framework of the MDA and the evidential burdens it creates. The appellants were charged under s 5(1)(a) of the MDA, with Dzulkarnain’s case involving delivery and Sanjay’s case involving possession for the purpose of trafficking, read with s 5(2). The Court emphasised that, in such cases, the Prosecution must prove the essential elements of the offence beyond reasonable doubt, while statutory presumptions may shift the evidential burden on certain issues, such as knowledge of the nature of the drugs under s 18(2).
On Dzulkarnain’s appeal, the Court of Appeal addressed the identity of the drug box. The trial judge had accepted the surveillance evidence: Dzulkarnain placed the Brown Box behind the Green Bin at the drop-off point, and shortly thereafter Sanjay retrieved a brown box from behind the same Green Bin. The Court of Appeal upheld the trial judge’s conclusion that the SKP Box seized from Sanjay was the same box that Dzulkarnain had left at the location. In doing so, the Court implicitly endorsed the trial judge’s approach to evaluating the reliability of the officers’ observations and the coherence of the timeline, including the short interval between the drop-off and retrieval.
On Sanjay’s procedural arguments, the Court of Appeal considered whether the trial judge had in fact relied on inadmissible statements. The grounds indicate that the trial judge had evaluated multiple statements recorded during investigations, including Sanjay’s contemporaneous statement under s 22 of the Criminal Procedure Code and other cautioned/long statements. The Court of Appeal’s dismissal suggests that it found either (a) the statements relied upon were admissible for the purposes used by the trial judge, or (b) even if there were defects, they did not affect the overall correctness of the findings on the material issues. The Court’s reasoning reflects a common appellate approach: procedural objections must be assessed in context, and convictions are not set aside for technical errors unless they occasion a miscarriage of justice.
Regarding the alleged lack of a unified Prosecution case theory, the Court of Appeal treated this as an argument about prejudice and coherence. The Court’s dismissal indicates that it did not accept that the Prosecution’s case was so inconsistent that it undermined the defence. Instead, the Court appears to have regarded the evidence as sufficiently consistent in its core narrative: the observed delivery mechanism (drop-off and retrieval), the seizure of the drug exhibits, and the statutory inferences arising from possession and knowledge. In drug cases, appellate courts often distinguish between minor inconsistencies in peripheral details and contradictions that go to the heart of the Prosecution’s proof.
The most substantive issue for Sanjay was the s 18(2) presumption. The trial judge had found that Sanjay’s involvement was limited to activities specified in s 33B(2)(a) of the MDA, but because the Prosecution did not issue Sanjay a certificate of substantive assistance (CSA), the mandatory death sentence applied. The Court of Appeal upheld the trial judge’s finding that Sanjay failed to rebut the presumption that he knew the nature of the drugs. This required the Court to assess Sanjay’s explanations about what he believed the box contained. The contemporaneous statement that he did not know what the SKP Box contained, alongside later shifting accounts, would be weighed against the plausibility of rebuttal evidence. The Court’s decision suggests that the trial judge found Sanjay’s explanations either not credible or insufficient to raise a reasonable doubt as to knowledge, or insufficient to satisfy the rebuttal standard on the balance of probabilities.
Finally, the Court of Appeal addressed Criminal Motion No 23 of 2022. Sanjay sought to adduce fresh evidence about the location of a duffel bag containing the drug exhibits, arguing that it would contradict CNB testimony and thereby affect the chain of custody. The Court of Appeal dismissed the motion, meaning it concluded that the proposed evidence did not meet the threshold for admitting fresh evidence at the appellate stage. While the full reasoning is not reproduced in the extract, the Court’s dismissal indicates that the evidence was either not sufficiently material, not credible enough to affect the outcome, or not properly justified as evidence that could not reasonably have been adduced at trial. Appellate remittal for further evidence is exceptional, particularly in capital drug cases where the trial judge’s findings are already based on extensive evidence and cross-examination.
What Was the Outcome?
The Court of Appeal dismissed both appeals: Criminal Appeal No 30 of 2020 (Dzulkarnain) and Criminal Appeal No 32 of 2020 (Sanjay). It upheld the High Court’s convictions on the charges pressed at trial and affirmed the sentences imposed. For Dzulkarnain, the Prosecution had issued a certificate of substantive assistance, so the trial judge imposed the alternative sentence of life imprisonment. For Sanjay, no CSA was issued, and the mandatory death sentence was imposed.
The Court of Appeal also dismissed Criminal Motion No 23 of 2022. As a result, Sanjay’s request for leave to adduce fresh evidence and for remittal to the trial judge to take further evidence on chain of custody was refused. The practical effect was that the convictions and sentences remained final.
Why Does This Case Matter?
This decision is significant for practitioners because it reinforces the appellate approach to three recurring themes in MDA prosecutions: (1) proof of identity and continuity of the drug exhibits, (2) the evaluation of statutory presumptions relating to knowledge, and (3) the high threshold for admitting fresh evidence on appeal, particularly where the proposed evidence concerns chain of custody.
First, the Court’s acceptance of the trial judge’s identity finding underscores the importance of a coherent evidential narrative. Where surveillance evidence establishes a drop-off and immediate retrieval at the same location, appellate courts are likely to treat the identity link as sufficiently proven unless there is a concrete evidential gap or credible alternative explanation. Defence strategies that focus on technical discrepancies without undermining the core timeline may face difficulty on appeal.
Second, the case illustrates how courts assess rebuttal of the s 18(2) presumption. Shifting accounts given in different statements, especially where a contemporaneous statement indicates lack of knowledge and later statements introduce new explanations, may be treated as undermining credibility. Practitioners should note that rebuttal is not achieved by merely asserting ignorance; it requires evidence capable of raising a real doubt or satisfying the relevant evidential burden, depending on the doctrinal framing applied by the courts.
Third, the dismissal of the fresh evidence motion signals that chain-of-custody challenges must be supported by evidence that is both material and properly admissible. Even where a defendant claims that an officer’s testimony about custody is contradicted, the appellate court will scrutinise whether the evidence could have been adduced at trial and whether it is likely to affect the outcome. This is particularly relevant for counsel preparing trial strategy: if chain-of-custody issues are to be pursued, they must be developed early and comprehensively.
